单选题On your answer sheet, circle and black out the letter that best answers the questions below.{{B}}Passage One{{/B}} Obviously, the per capita income of a country depends on many things, and any statistical test that does not take account of all important determinants is misspecified, and thus must be used only for descriptive and heuristic purposes. It is nonetheless interesting--and for many people surprising--to find that there is a positive and even a statistically significant relationship between these two variables: the greater the number of people per square kilometer the higher the per capita income. The law of diminishing returns is not invariably true. It would be absurd to suppose that a larger endowment of land ipso facto makes a country poorer. This consideration by itself would, of course, call for a negative sign on population density. Thus, it is interesting to ask what might account for the "wrong" sign and think of what statistical tests should ultimately be done. Clearly there is a simultaneous two-way relationship between population density and per capita income; the level of per capita income affects population growth just as population, by increasing the labor force, affects per capita income. The argument offered here suggests that perhaps countries with better economic policies and institutions come to have higher per capita incomes than countries with inferior policies and institutions, and that these higher incomes bring about a higher population growth through more immigration and lower death raters. In this way, the effects of better institutions and policies in raising per capita income swamps the tendency of diminishing returns to labor to reduce it. This hypothesis may also explain why many empirical studies have not been able to show a negative association between the rate of population growth and increases in per capita income. One reason why the ratio of natural resources to population does not account for variations in per capita income is that most economic activity can now readily be separated from deposits of raw material and arable land. Over time, transportation technologies have certainly improved, and products that have a high value in relation to their weight, such as most services and manufactured goods like computers and airplanes, may have become more important. The Silicon Valley is not important for the manufacturing of computers because of the deposits of silicon, and London and Zurich are not great banking centers because of fertile land. Even casual observation suggests that most modem manufacturing and service exports are not closely related to natural resources. Western Europe does not now have a high ratio of natural resources to population, but it is very important in the export of manufactures and services. In a parallel way, the striking success of Japan, Hong Kong, and Singapore, with relatively few natural resources per capita, cannot be explained by reliance thereon.

单选题The one accident situation where immediate action must be taken is when a person stops breathing. This might be the result of drowning, electrocution, suffocation, head injury caused by a fall, poisoning or a variety of other accidents. If someone has stopped breathing, however, there may be a simpler cause—the breathing passages may be blocked by food, vomit, saliva or even the tongue... Whatever the cause, it is imperative that breathing is restarted quickly, as otherwise brain damage may result. Act quickly: lay the casualty flat on his back, and pull back the head while holding the jaws clenched. This prevents the tongue from falling back into the throat and blocking the air passages. If any foreign matter like sand or vomit can be seen in the victim's mouth or throat, scoop it out with the fingers. False teeth are a particular hazard and often fall back into the throat of an unconscious person. If breathing does not start immediately, you must begin artificial respiration right away, by breathing directly into the casualty's lungs through the mouth or nose... As you exhale deeply through the casualty's nose, it is necessary to hold their mouth firmly closed. If you are breathing into the mouth, however, pinch the nostrils to stop the escape of air. If the airways are not obstructed you will see the chest of the casualty's lungs. Each time you blow, turn your head to check that there is regular rise and fall of the chest. This must be continued until breathing starts spontaneously, or in any event for at least an hour. As soon as the casualty starts to respond you should see an improvement in his colour, usually after the first dozen or so inflations. When breathing starts, it will be weak and shallow, and will still need assisting. Time your breaths to coincide with those of the casualty, as his breathing gradually strengthens. When breathing has restarted and can continue without help, the casualty will still be unconscious. He should be turned into the "unconscious'' position, preferably with the body slightly higher than the head, and watched carefully to make sure that breathing continues. Don't rush to get him to hospital. It is more important to make sure that breathing is strong and will continue while the casualty is being moved.

单选题The question of whether war is inevitable is one which has concerned many of the world's great writers. Before considering this question, it will be useful to introduce some related concepts. Conflict, defined as opposition among social entities directed against one another, is distinguished from competition, defined as opposition among social entities independently striving for something which is in inadequate supply. Competitors may not be aware of one another, while the parties to a conflict are. Conflict and competition are both categories of opposition, which has been defined as a process by which social entities function in the disservice of one another. Opposition is thus contrasted with cooperation, the process by which social entities function in the service of one another. These definitions are necessary because it is important to emphasize that competition between individuals or groups is inevitable in a world of limited resources, but conflict is not. Conflict, nevertheless, is very likely to occur, and is probably an essential and desirable element of human societies. Many authors have argued for the inevitability of war from the premise that in the struggle for existence among animal species, only the fittest survive. In general, however, this struggle in nature is competition, not conflict. Social animals, such as monkeys and cattle, fight to win or maintain leadership of the group. The struggle for existence occurs not in such fights, but in the competition for limited feeding areas and for occupancy of areas free froth meat-eating animals. Those who fail in this competition starve to death or become victims to other species. This struggle for existence does not resemble human war, but rather the competition of individuals for jobs, markets, and materials. The essence of the struggle is the competition for the necessities of life that are insufficient to satisfy all. Among nations there is competition in developing resources, trades, skills, and a satisfactory way of life. The successful nations grow and prosper; the unsuccessful decline. While it is true that this competition may induce efforts to expand territory at the expense of others, and thus lead to conflict, it cannot be said that war-like conflict among nations is inevitable, although competition is.

单选题Electronic mail has been in widespread use for more than a decade, simplifying the flow of ideas, connecting people from distant offices and eliminating the need for meetings, but E-mail should be carefully managed to avoid unclear and inappropriate communication. As time goes on, and more people surf the Net, the amount of unsolicited e-mail grows. Some folks reasonably assume that cyberspace mirrors many aspects of other forms of communications. It would seem that since telemarketing and direct mail are successfully used as marketing techniques for many businesses, it should follow that direct e-mail, or unsolicited e-mail, should also work. This topic is hotly debated between experienced Internet users and newcomers. Unlike receiving promotional materials through the mail or over the phone, e-mail does carry a cost to the recipient. "Bandwidth" is used every time an e-mail message is sent and places a load on existing resources. The process of sending unsolicited e-mail to large, untargeted lists, or through mailing list discussion groups or Usenet newsgroups, is known as "spamming". Spamming wastes bandwidth. Imagine if it became common practice for businesses to market this way. Not only would it be annoying for many, the load on the system would translate to higher access fees. Unlike regular mail where the sender pays the cost of delivering the mail, e-mail is cheap to send, and in some cases, expensive to receive. Many businesses responsibly market by e-mail, for example, by inviting existing customers or website visitors to receive future e-mail announcements. Some of the free e-mail services are advertiser supported and hence using e-mail marketing in an up front acceptable manner. Hopefully, this will be the norm, rendering the inconvenience of spam a thing of the past.

单选题 Fear and its companion pain are two of the most useful things that men and animals possess, if they are properly used. If fire did not hurt when it burnt, children would play it until their hands were burnt away. Similarly, if pain existed but fear did not, a child would burn itself again and again, because fear would not warn it to keep away from the fire that had burn it before. A really fearless soldier-and some do exist-is not a good soldier because he is soon killed; and a dead soldier is of no use to his army. Fear and pain are therefore two guards without which men and animals might soon die out. In our first sentence we suggested that fear ought to be properly used. if, for example, you never go out of your house because of the danger of being knocked down and killed in the street by a car, you are letting fear rule you too much. Even in your house you are not absolutely safe: an airplane may crash on your house, or ants may eat away some of the beams in your roof so that the latter falls on you, or you may get cancer! The important thing is not to let fear rule you, but instead to use fear as your servant and guide. Fear will warn you of dangers; then you have to decide what action to take. In many cases, you can take quick and successful action to avoid the danger. For example, you see a car coming straight towards you; fear warns you, you jump out of the way, and all is well. In some cases, however, you decide that there is nothing that you can do to avoid the danger. For example, you cannot prevent an airplane crashing onto your house. In this case, fear has given you its warning; you have examined it and decided on your course, of action, so fear of this particular danger is no longer of any use to you, and you have to try to overcome it.

单选题2 Analysts have had their go at humor, and I have read some of this interpretative liter ature, but without being greatly instructed. Humor can be dissected, as a frog can, but the thing dies in the process and the innards (内在部分) are discouraging to any but the pure scientific mind. In a newsreel theatre the other day I saw a picture of a man who had developed the soap bubble to a higher point than it had ever before reached. He had become the ace soap bubble blower of America, had perfected the business of blowing bubbles, refined it, doubled it, squared it, and had even worked himself up into a convenient lather. The effect was not pretty. Some of the bubbles were too big to be beautiful, and the blower was always jumping into them or out of them, or playing some sort of unattractive trick with them. It was, if anything, a rather repulsive sight. Humor is a little like that: it won't stand much blowing up, and it won't stand much poking. It has a certain fragility, an evasiveness, which one had best respect. Essentially, it is a complete mystery. A hu man frame convulsed with laughter, and the laughter becoming mysterious and uncontrol lable, is as far out of balance as one shaken with the hiccoughs or in the throes of a sneez ing fit. One of the things commonly said about humorists is that they are really very sad peo ple-clowns with a breaking heart. There is some truth in it, but it is badly stated. It would be more accurate, I think, to say that there is a deep vein of melancholy running through everyone's life and that the humorist, perhaps more sensible of it than some oth ers, compensates for it actively and positively. Humorists fatten on trouble. They have al ways made trouble pay. They struggle along with a good will and endure pain cheerfully, knowing how well it will serve them in the sweet by and by. You find them wrestling with foreign languages, fighting folding ironing boards and swollen drainpipes, suffering the terrible discomfort of tight boot (or as Josh Billings wittily called them, "tire boots"). They pour out their sorrows profitably, in a form that is not quite a fiction not quite a fact either. Beneath the sparking surface of these dilemmas flows the strong tide of human woe. Practically everyone is a manic depressive of sorts, with his up moments and his down moments, and you certainly don't have to be a humorist to taste the sadness of situation and mood. But there is often a rather fine line between laughing and crying, and if a hu morous piece of writing brings a person to the point where his emotional responses are un trustworthy and seem likely to break over into the opposite realm, it is because humor, like poetry, has an extra content. It plays close to the big hot fire, which is Truth, and sometimes the reader feels the heat.
